Hi folks,

In the upcoming L release Murano is going to use the "Glance Artifact
Repository" feature implemented as part of EXPERIMENTAL Glance V3 API.

The server-side support of this feature is already merged in glance's
master branch, while the client code is not: it was agreed that the v3's
client will stay in a dedicated feature branch (feature/artifacts) and will
not be released until the API is stable and final (a major API refactoring
based on the feedback from API WG is on the way and is likely to happen in
M). So, there will be no v3-aware releases of python-glanceclient on pypi
until then. The early adopters of V3 API are encouraged to build the
tarballs out of the feature branch on their own and use them, keeping in
mind that the API is EXPERIMENTAL so everything may be (and will be)
changed.

However, Murano needs some way to consume Glance V3 right now, and  - as it
has a voting requirements job at the gate - it cannot just put a git branch
reference in its requirements.txt. It needs some kind of a release which
would be part of global requirements etc.

So, it was decided to temporary copy-paste the experimental part of glance
client into the murano client (i.e. to copy
python-glanceclient/feature/artifacts/v3 to
python-muranoclient/master/artifacts) and release it as part of several
next releases of python-muranoclient.

When the Glance V3 API is stable, we'll put its client to the master branch
of python-glanceclient and release it normally, then dropping the temporary
copy from python-muranoclient.

Until then, all the changes to the experimental client should be done in
the feature/artifacts branch of glance client and copied (synced) to murano
client. Similar to oslo.incubator sync procedure, just without a shell
script :)

I hope that the need to do this copy-pasting will not last for long and the
v3 API becomes stable soon enough.
